Facebook's Mark Zuckerberg announced today a potentially life-saving -- and possibly TMI -- new feature: Facebook users now have the option to share their organ donor status on their timelines. In a post on the site, Facebook points out that there are 114,000 people currently awaiting transplants in the U.S., and millions around the world.

"Medical experts believe that broader awareness about organ donation could go a long way toward solving this crisis. And we believe that by simply telling people that you're an organ donor, the power of sharing and connection can play an important role."

The new timeline feature provides links to organ donation registries in the event that someone wants to sign up, and currently is only available in the U.S. and the U.K. Widespread rollout is planned in the coming months.
